Which is, in your opinion, the greatest ever driver pairing? And by that I mean two drivers that had mutual respect and who were team players while fighting each other for the championship. Like Scheckter – Villeneuve in 79 or Button – Hamilton in recent years.

This is quite a bit biased, but I really really liked the combination Raikkonen-Massa from 2007 to halfway 2009. With them Ferrari took 2 consecutive constructor titles. Only the combination Alonso-Hamilton could beat them back in 2007.
(that’s a modern driver pairing, other than that Raikkonen-Montoya were a great pairing, Hakkinen-Coulthard too, and from the eighties Prost-LAuda)

For me it simply has to be Senna-Prost in the McLaren, but I also think that the Stewart-Cevert partnership of 1973 was fantastic, and if their times had been shifted more towards each other and Cevert hadn’t lost his life, they may have been outstanding.
